Up to the 1990s there were workstations designed for software development (Lisp/Smalltalk Machines by various vendors), graphics and CAD (Apollo, SGI), and general purpose systems (Sun, HP).
Was Xerox Star the only office workstation?
Were there other dedicated workstations (not high-end PCs or Macs) designed for office and business tasks? Of course there were word processing machines. But I’m not sure they qualify as they didn’t play in the same league as the Star and were much less versatile.
I feel like most offices would use the general purpose machines.
That’s likely, but I wonder whether any other office workstations were actually developed.
